AUTOMATED BLOOD COMPONENT SEPARATION PROCEDURE AND APPARATUS PROMOTING DIFFERENT FUNCTIONAL CHARACTERISTICS IN MULTIPLE BLOOD COMPONENTS

摘要

Method and apparatus are provided for machine separation of blood into blood components, wherein a preselected fluid such as anticoagulant is added to at least two different locations (16, 112) through the fluid flow path of the sec (10), in order to promote the different functional characteristics in different blood components. The method results in reduced incidence of citrate reaction in the blood donor and increased platelet yield in platelet rich plasma (60) collected during the procedure.
